Kua tāruatia ki te papatopenga
\left(T-2\right)\left(T^{2}+2T+4\right)
Tuhia anō te T^{3}-8 hei T^{3}-2^{3}. Ka taea te rerekētanga o ngā pūtoru te whakatauwehe mā te whakamahi i te ture: a^{3}-b^{3}=\left(a-b\right)\left(a^{2}+ab+b^{2}\right). Kāore te pūrau T^{2}+2T+4 i whakatauwehea i te mea kāhore ōna pūtake whakahau.
